Feed-Works for Machine-Tools
|
William N. Stevens |
Bridgeport, Fairfield County, CT |
Abstract:
This invention relates to new and useful improvements in feed works for machine tools and refers particularly to mechanism for operating the head that carries the cutting tools.
While the feed works is susceptible of a wide application to machines of various types, yet it will be seen that it is illustrated in connection with a novel type of multiple spindle machine of the general type and character shown and described in a prior application on a multiple spindle machine #811,198 filed Jan. 9, 1914. (Patent #1,258,089.) This feed works is particularly useful in connection with a machine of this type or in fact any machine which includes an operatable tool carrying slide that is adapted to be operated by a feed screw, as is the case with this machine, which is now commercially known as the Mult-Au-Matic.
The purpose. of this invention is to provide an improved design which does not alone perform a simple feeding operation of the tool carrying slides, but
one which includes a quick forward movement of the feed screw to bring the cutting tool in position for operation; and which further comprises means for then connecting the feed for the cutting tool; further to provide automatic means for tripping the operating or cutting feed when its work is completed and quickly returning the slide to its starting position preparatory to a further operation.
A further object of the invention is to overcome objections now existing in other forms of feeds, whereby a more powerful and rigid feed may be had including the use adording an opportunity and the ability of change; gears for cutting exact pitches, to operate said feed works by hand independent of the other feed works on the machine sending it through all or part of its cycle of operations as occasion requires, finally to provide a load weighing or regulating device whereby the load under which the head is feeding may be predetermined and set to insure uniform operations, and further to provide means whereby an excessive load will engage the clutch to return the head to its position of rest.
Claim:
ln a feed works of the class described, the combination of a tool slide, a threaded element, a feed screw, means for quickly driving the same in a forward direction to place the slide in position for operation, means for advancing the feed screw for the feeding operation, a pivoted weighted arm for regulating the pressure under which the screw may operate, and means for rapidly driving the screw in a reverse direction to return the slide. |

Floating Chuck
|
Arthur A. Tomenceak |
Bridgeport, Fairfield County, CT |
Claim:
So-called floating chuck jaw assemblies are employed on centered work in lathes for the purpose of ensuring accurate alignment of the centers of the machine and the centers of the workpiece to be machined. They are designed to prevent uneven forces from being applied to the work in gripping it, which forces tend to move the work off the machine centers. |

Chuck
|
Ernest H. Johnson |
Bridgeport, Fairfield County, CT |
Claims:
All chucks have inherent inaccuracies in that manufacturing tolerances for machining the jaw ways results in the center lines of the jaw ways intersecting at points other than the true center of rotation of the chuck spindle.
Cylindrical work to be properly gripped by a set of chuck top-jaws requires two fundamental conditions to be met, namely, the work-engaging surfaces of the top-jaw inserts must be absolutely concentric with the center of rotation of the work-rotating spindle, and the radial distance of the work-engaging surface of the top-jaw inserts must be identical.
These two fundamental requirements have led to the fabrication of top-jaw inserts by a method that requires final turning and/or grinding of the work-engaging surfaces thereof while the top-jaws are attached to the work-supporting spindle with which they ultimately, are to be employed. The attending disadvantages of top- jaw inserts made by such a method are manifest. Down time for replacing top-jaw inserts is harmful to production schedules and particularly so in those cases where multiple spindle machines are concerned; interchangeability of top-jaws is impossible because only the inserts of top-jaws for a given spindle are accurate enough for that spindle; damage to any one top-jaw insert requires as much down time to replace it as would be required to replace an entire set of top-jaw inserts; and accuracy in chucking is limited because variations in chucking pressures causes unpredictable stress and strain variations in the links of the chuck-jaw actuating mechanism resulting in material run out during a turning operation, which requires resurfacing the inserts for every substantial change in chucking pressures.
The principal object of this invention is to provide a chuck-jaw assembly including a completely prefabricated top-jaw insert that is at all times interchangeable with comparable inserts employed with top-jaws for any work-supporting spindle.
Other objects include the provision of a top- jaw insert adapted to be adjusted radially, as well as angularly, relatively to the top-jaw to which it is attached; the provision of such a top- jaw insert which can be adjusted relatively to its supporting top-jaw to compensate for unpredictable strains and stresses in the jaw-actuating linkage; and the provision of a chuck-jaw construction in which a radially-movable lower jaw supports a top-jaw that in turn supports a top- jaw insert for movement along the longitudinal axis of the lower jaw, as well as for pivotal movement about a point located along said axis.
Other objects include the provision of such a, top-jaw in which an insert is, capable of being adjustably mounted for maintaining-its prefabricated work-engaging surface in perfect concentricity with the axis of rotation of the work- supporting spindle with which it is employed; the provision of such a top-jaw and insert therefor that employs a single mounting member to provide pivotal adjustment, of the insert about a point and radial adjustment relatively to the axis of rotation of the spindle with which such- top-jaw and insert are to be employed. |

Chuck

Joseph C. La Mastra |
Stratford, Fairfield County, CT |
Claim:
The gripping of thin-walled workpieces in chucks during turning operations has always presented a serious problem, particularly where tolerances are at all critical. In the past thin-walled workpieces have usually been held in three- and four-jaw chucks, either by an external contracting action or an internal expanding action. Such chuck actuation causes distortion of the thin-walled workpiece to such an extent that although accurate turning of the workpiece could be effected, release of the workpiece from the chuck would cause distortion of the workpiece to such an extent that it was impossible to maintain the required tolerances in many instances. Various modifications of the chuck jaw surfaces including the increasing of the area of contact between the jaw surfaces and the workpiece have, in some instances, lessened the condition of distortion, however, all of the known prior art modifications to overcome this difficulty have not satisfactorily solved the problem.
The principal object of the present invention is to provide a chuck construction that will rigidly grip a thin- walled workpiece and maintain it in an undistorted condition throughout a working operation thereon. |

Contour Machining
|
Arthur A. Tomenceak |
Fairfield, Fairfield County, CT |
Abstract:
The disclosure relates to techniques in equipment for the machining with single point tooling of non-circular shapes and contours. The procedure according to the invention involves the use of a rotary cutting head, carrying one or more cutting tools, arranged to be advanced axially to accomplish internal boring or external turning of non-circular shapes. The cutting head, which may be considered either a boring head or a turning head, depending on whether the cut is taken internally or externally, is mounted for controlled advancing and retracting movements along its rotational axis. The cutting tools themselves, which are carried by the cutting head, are mounted for controlled radial extending and retracting movements as a function of the rotational position of the spindle. The extending and retracting movements of the cutting tool or tools is controlled by means of a pre-shaped contour cam mounted in fixed relation to the workpiece. During each rotation of the spindle, the cutting tools are extended and retracted according to the pattern of the contour cam, resulting in a contoured, non-circular, cutting or boring of the workpiece. Because the tool-carrying spindle rotates, while the work remains stationary, the centrifugal force created by the spindle rotation is used to great advantage to assist in controlling movement of the tool slide in accordance with the path determined by the contour cam.
The process and apparatus of the invention can be utilized to outstanding advantage in connection with the machining of epitrochoidal chambers for rotary combustion (e.g., Wankel) engines. Significant process aspects of the invention are directed to that end. In this connection, the invention involves the two-stage machining of an epitrochoidal chamber, with the spindle axis of the machine offset a predetermined distance from the plane dividing the two principal lobes of the chamber. In accordance with an important aspect of the invention, by off-setting the spindle axis along the major axis of the chamber, to be located a short, predetermined distance from the transverse dividing plane, an entire half of the epitrochoidal chamber may be machined in one pass of the spindle, using single point cutting tools. The spindle axis is then symmetrically repositioned in offset relation on the opposite side of the dividing plane, to effect machining in a single pass of the other half of the chamber. This extraordinary technique permits exceptional time economies to be realized in the machining of the combustion chamber while at the same time achieving much greater levels of accuracy than has been obtainable with conventional machining processes.
Claim:
A contour machining apparatus comprising
a. a normally non-rotatable workpiece support,
b. a spindle housing arranged for relative axial movement toward and away from the workpiece support,
c. a spindle rotatably mounted in said housing and having a tool head at one end facing the workpiece support,
d. a tool slide mounted on said tool head for slideable movement transverse to the axis of the spindle,
e. cam follower means movable with said tool slide,
f. a contour cam mounted in normally non-rotatable relation to the spindle housing and positioned in cooperative relation to said cam follower means,
g. said spindle, slide, cam follower means and cam being so oriented and related that centrifugal force on said tool slide, resulting from rotation of said spindle, operates to urge the cam follower means against the cam, and
h. auxiliary tool control means urging said cam follower means against said cam independently of centrifugal force. |

This is a division of application Ser. No. 305,653, filed 11/13/72, now U.S. Pat. No. 3,822,618.
Abstract:
The disclosure relates to techniques in equipment for the machining with single point tooling of non-circular shapes and contours. The procedure according to the invention involves the use of a rotary cutting head, carrying one or more cutting tools, arranged to be advanced axially to accomplish internal boring or external turning of non-circular shapes. The cutting head, which may be considered either a boring head or a turning head, depending on whether the cut is taken internally or externally, is mounted for controlled advancing and retracting movements along its rotational axis. The cutting tools themselves, which are carried by the cutting head, are mounted for controlled radial extending and retracting movements as a function of the rotational position of the spindle. The extending and retracting movements of the cutting tool or tools is controlled by means of a pre-shaped contour cam mounted in fixed relation to the workpiece. During each rotation of the spindle, the cutting tools are extended and retracted according to the pattern of the contour cam, resulting in a contoured, non-circular, cutting or boring of the workpiece. Because the tool-carrying spindle rotates, while the work remains stationary, the centrifugal force created by the spindle rotation is used to great advantage to assist in controlling movement of the tool slide in accordance with the path determined by the contour cam.
The process and apparatus of the invention can be utilized to outstanding advantage in connection with the machining of epitrochoidal chambers for rotary combustion (e.g., Wankel) engines. Significant process aspects of the invention are directed to that end. In this connection, the invention involves the two-stage machining of an epitrochoidal chamber, with the spindle axis of the machine offset a predetermined distance from the plane dividing the two principal lobes of the chamber. In accordance with an important aspect of the invention, by offsetting the spindle axis along the major axis of the chamber, to be located a short, predetermined distance from the transverse dividing plane, an entire half of the epitrochoidal chamber may be machined in one pass of the spindle, using single point cutting tools. The spindle axis is then symmetrically repositioned in offset relation on the opposite side of the dividing plane, to effect machining in a single pass of the other half of the chamber. This extraordinary technique permits exceptional time economies to be realized in the machining of the combustion chamber while at the same time achieving much greater levels of accuracy than has been obtainable with conventional machining processes. |

Vertical Lathe with Automatic Tool Change Facility
|
Claude M. Grinage |
Stratford, Fairfield County, CT |
Abstract:
The disclosure relates to a tool change system for a vertical lathe or the like which, among other things, greatly reduces the nonproductive time of the machining head. During machining with a first tool, a second tool is selected from a storage library and is transported over to the ram housing from which the ram and cutting tool are supported. The new tool, held by the transfer carrier, remains in a predetermined position with respect to the ram housing, even though the latter is moving in the course of machining operations. When the machining program subsequently calls for a tool change, it is only necessary to retract the ram, and the tool is waiting to be installed. A unique arrangement of torque limiting clutch enables the transfer carrier to follow the movements of the ram housing in the desired manner in preparation for the tool change to be executed.
The disclosure also relates to an improved "flow-through" arrangement for effecting tool change, whereby a new tool is slid into position from one side of the ram, while the used tool simultaneously slid out of engagement with the ram from the opposite side. A two-pronged loader simultaneously engages both the new and old tools to effect the desired flow-through tool exchange motion.
The new apparatus includes advantageous arrangements for eccentrically mounting right-hand and left-hand tools in the machine ram. Control means are provided for properly positioning the transfer carrier and loader means, taking into account the left-hand or right-hand character of both the new and used tools. Provision for eccentric mounting of the tools enables a much heavier and stronger ram to be employed.
Significant reductions are realized in the nonproductive time of the machine, required to effect a tool change, first because the new tool is always in position immediately adjacent and moving along with the ram housing, and second because of the provision for flow-through tool exchange. As soon as the two-pronged loading device has cleared the used tool from the back side of the ram and has withdrawn from the newly positioned tool, the ram can be returned to machining position and machining operations can resume. The balance of the tool change sequence, involving return of the used tool to a transfer carrier and transport by the carrier to the tool library, and the subsequent selection and transfer over to the ram housing of a new tool, all can take place after machining operations have been resumed. |

Clamping Means for a Tool Block in the Vertical Boring Machine or the Like
|
Claude M. Grinage |
Stratford, Fairfield County, CT |
Abstract:
In a tool change system for a vertical lathe or the like, a new and improved arrangement for clamping a tool block in a tool supporting ram. The new clamping means provides a firm support for the tool block and further includes means for equalizing the clamping forces applied to the tool block and for properly positioning and orienting the tool block in the ram. In accordance with a specific feature of the present invention, the tool block is provided with clamp engaging means on opposite sides thereof and the clamping means comprises a pair of spaced clamping bars engageable with the respective clamping means on the tool block. A common actuating means is operative to move the clamping bars into a tight clamping relation with the clamping means of the tool block. Means are provided for effectively distributing the clamping force applied by the actuating means which comprise a first connecting means for yieldably interconnecting the actuating means to one of the clamping bars and a second connecting means for non-yieldably interconnecting the actuating means to the other of the clamping bars. The non-yieldable second connecting means is arranged on the side of the tool block from which the work approaches.
